时序信息加工机制及其通道效应的实验研究 总被引:5,自引:2,他引:3
研究由两个实验组成,实验一采用纯粹的视听方式,以线段长度和声音频率为材料,对时序信息的加工方式(自动加工与控制加工)、编码特点(时序信息是何时编码的)以及通道效应进行了研究。实验二以汉字为材料重复实验一的过程;结果表明,时序信息的加工存在视听通道效应,其机制源于记忆,且与实验材料的加工深度以及加工方式有关;时序信息既包含有自动加工,又包含有控制加工。视觉刺激倾向于自动加工,而听觉则倾向于控制加工;时序信息是在项目学习时编码获得的,而不是在提取时建构的。 相似文献

Inverted alphabet printing, rotary pursuit, and mirror tracking tasks were administered to 84 subjects in order to ascertain (a) reproducibility of reminiscence scores within and between tasks and (b)sex differences in reminiscence. With prerest performance levels held constant by second-order partial correlation procedures, reproducibility of individual reminiscence differences within tasks was significant but quite low, while predictability of reminiscence from one task to another was negligible. The sexes reminisced essentially alike on inverted alphabet printing, but females reminisced more than males on the other tasks, presumably because they were relatively more depressed by massed practice on these tasks. Thus, individual and sex differences were essentially task specific. Implications of results for reminiscence theories and for the credibility of alleged relationships between reminiscence and other organismic variables were discussed. 相似文献

Four types of bilinguals solved simple addition problems that were auditorily presented in their preferred language, the language in which they first learned arithmetic, or in their nonpreferred language. Subjects responded in the language in which the problems were presented. Solution time averaged .227 sec faster in the preferred language and was an increasing linear function of the number of addition operations required. The intercepts of the preferred and nonpreferred language functions significantly differed, but the slopes did not. The preferred language advantage was attributed to faster encoding and/or response times in the preferred language. When bilinguals used only one of their languages in a given experimental session, encoding/response times in the two languages were equivalent and the preferred language advantage was eliminated. 相似文献

本文从唐伯元的治学经历入手,探讨他的学术、思想的渊源与主要内涵:唐伯元心性论的基本结构,他对性与身、心与物、理与欲的看法;在此基础上,他将修身看作一个包容着齐家治国平天下的渐次扩展的过程,以此为孔门学问之要旨;因此,他批评阳明学派“以心为学”的倾向,并着力推崇“礼”学,以礼为儒者内外双修、成己成物的必须遵循的途径。 相似文献

The study describes the sulcal and gyral topography, variability, and left-right asymmetry of the parietal operculum. Eighty postmortem hemispheres as well as sagittal magnetic resonance images from 20 health volunteers (40 hemispheres) were evaluated. Four different types of parietal opercular sulcus topography were recognized. Most frequently, and conforming with the anatomic "textbook pattern", the inferior postcentral sulcus (POCS) is the sulcus anterior to the posterior ascending ramus (PAR) of the Sylvian fissure (type 1). Variations were the following: lack of a PAR (type 2), interposition of an intermediate opercular sulcus and gyrus between PAR and POCS (type 3), and direct transition of PAR into POCS with subsequent lack of a classical supramarginal gyrus (type 4). Inconstancy of the sulcal standard arrangement was especially pronounced among left hemispheres, where the patterns differed from type 1 in one third of the cases. Types 2 and 3 were significantly more frequent in left hemispheres, whereas type 4 occurred significantly more frequently in right hemispheres. Upon intraindividual left-right comparison, a remarkable 38% of the brains showed gross asymmetry of the parietal opercular sulcus patterns, characterized by a left type 2 or 3 and/or a right type 4; another 5% exhibited a reverse type of asymmetry. The findings supplement previous data on gross variability and left-right asymmetry of the posterior Sylvian fissure and its lower bank. They indicate that the Sylvian fissure is an unreliable landmark with respect to inferior parietal structures especially in left hemispheres. Individual mapping of perisylvian topography may contribute to studies on structural-functional relationship. 相似文献

时间词义赋值特征的分析 总被引:8,自引:2,他引:6
本研究用模糊统计试验方法对9个时间修饰词作了经验赋值工作。被试260名本科大学生和160名高中生。结果表明,给定的9个时间修饰词都是模糊概念,其中“此刻”的模糊度最小,“将来”和“过去”的模糊度最大,“不久”的模糊度较大。对大学生来说,9个时间修饰词的模糊度由小到大的排列顺序为“此刻”、“刚才”、“现在”、“即将”、“遥远的未来”“很久以前”“不久”“过去”“将来”。对高中生来说,9个时间修饰词的模糊度由小到大的排列顺序为“此刻”、“现在”、“刚才”、“即将”、“遥远的未来”、“很久以前”、“不久”、“过去”、“将来”。词义的模糊度与评量的把握度呈负相关。给定的9个时间修饰词在心理量表上的距离是不等的。 相似文献

This research designed three experiments to investigate the mechanism of how imagery perspective influences decision difficulty, which increases consumers' willingness to postpone making choices based on the construal level. Studies 1, 2, and 3 demonstrated that imagining from the actor's perspective lowers one's construal level, and thus leads to greater decision difficulty and willingness to postpone making choices. In comparison, those taking the observer perspective represent things at higher construal levels and have less difficulty making decisions or willingness to postpone making choices. Moreover, the derived results showed the need for cognition to moderate the relationship between imagery perspective and construal level. The findings herein extended the physical buying situation to online consumption, providing implications for marketers to further explore consumer behavior. 相似文献

Traditionally, researchers employ human raters for scoring responses to creative thinking tasks. Apart from the associated costs this approach entails two potential risks. First, human raters can be subjective in their scoring behavior (inter-rater-variance). Second, individual raters are prone to inconsistent scoring patterns (intra-rater-variance). In light of these issues, we present an approach for automated scoring of Divergent Thinking (DT) Tasks. We implemented a pipeline aiming to generate accurate rating predictions for DT responses using text mining and machine learning methods. Based on two existing data sets from two different laboratories, we constructed several prediction models incorporating features representing meta information of the response or features engineered from the response’s word embeddings that were obtained using pre-trained GloVe and Word2Vec word vector spaces. Out of these features, word embeddings and features derived from them proved to be particularly effective. Overall, longer responses tended to achieve higher ratings as well as responses that were semantically distant from the stimulus object. In our comparison of three state-of-the-art machine learning algorithms, Random Forest and XGBoost tended to slightly outperform the Support Vector Regression. 相似文献
